Petten ted June 5, `191'?.

Application filed August 1.3, 1913. Serial No 'ldlih To all ywhom t may concern:

Be it known that I, lltlnnrr T. Knnnnm, u, citizen of the United States of America, and e resident of Buffalo, in the eoui'ity of Erie sind Starte of New Yorin here invented new and useful llnprm'einents in '.llhrust Bearingsjof which the following is e speci fieation.

Figure l is e seetionnl `View showing my invention applied to e vehicle hub7 Fig, 2' e transverse seetion ol the thrust i tion is to improve the type'ot thrust bearing eoveredby my `lornler Patent, No. 939,2tl9 November 9, 1909, rendering' that type of bearing more sensitive end delieete in operetiorn to thereby eliininnte e lurge portion oli' the i'rietion which, occurs before the thrust bearing comes into 'full notion., and to also render the bearing, to use e elmp 'tenen fooleproof, :in 'that the :uljustnu-,nt of the parte i'ieed be requireh if et ull1 only et long intervals' :ind een be neeonlljnlished then only7 by disnnnitling the benring, es more fully hereinafter eet forth.

'Referring to the drnwilue by reterei'iee chnraeters, a designates the .i j.ntioiuiry ineinber of the bearing, which in they pressent instance, e vehicle axle and Zi the rotnry member, thisl being in the present instnnee a, vehicle lu'ilo. The redini or loiu'lei,istui1i ing hearings consist of two 'sets ol3 li'mde'sustaining rollers c, one heini;r :it euli end These rollers beer it )on en inner sleeve rl nllixed to the :ixle und en outer sleeve e removelily set in the hub.

The sleeve o ie provided with eerresponding; ontw; 'diy exteiulii'le; l'lnnges Q :ind fj, the lutter being renmruble. 'lll'ieee [longed Sleeves forno ein :nmulnr channel in n'llieli. the rune rinoe are freely inelosed, bei.v it siuiniorted by A nflrnie. The outer corners ot" the inner liueee ol the rece ringe ure bei'eled oli nt n und thee beveled nni'iulnr ineen rest upon Siniilan y beveled teures; ut the pointure oilE the flanges (j und. q und the body ol.2 the sleeve end thus tend to bring the two rateo rings together upon the interpoeeiil rollers by; e ouin-like notion The outer corners of the rece rings :ire sil'uilrn'ly beveled off et s :lull these beveled parte u re udupted to come into eontuet et ifertuin 'tiene with eiinilnrljif beveled unnulur surfaces :formed on the zio outer sleeve ln, at the juncturethereof with its flanges p p. j

It will be observed that the proportions of the parts are such that when the race rings are in-place they hang loosely on the l beveled faces of the inner sleeve, there being a vclearance at all points between the race rings and the surrounding parts, so that when the rotary member of the bearing is subjected to no end thrust in y"either direction, the thrust bearing will be entirely idle. The action of the thrust bearing will be fully understood byfollovving the action of the members when an outward thrust comes upon the hub; when the hub is subjected to such a thrust the Afollowing action takes place: The left hand beveled face ofthe sleeve n firstengages an adjacent beveled i face 0n the adjacent race ring andif the thrust is suicient, the opposite ringwill be swung or pushed against the right hand flange of the sleeve oV and at the same time the adjacent race ring will be (by reason 0f the lcam-like action ofV the beveled face) lifted sufficiently to be freed' entirely from the sleeve '0, whereupon it rotates With the hub. If the thrust be sufficient, the left hand race ring will be brought solidly into contact with the flange g', and will rotate with the hub, and the right hand race ring will be jammed hard against the flange g and will be held stationary by the axle. T he same movement ofthe parts, but` inthe reverse order, will take place when the thrust on .the vehicle hub is in the opposite direction, s

It will be seen from the foreging that my present improvements differ from my former patented structure' heretofore referred to 1n that the outer or rotary member of the bearing is provided with annular beveled or cam faces which serve to shift 0r take up one of the race rings and relieve it of contact with the nen-rotary member of the bearing upon the slightest thrust. In this Way I eliminate all of the rubbing action between the surface of the parts constituting the thrust bearing and thus render the thrust bearing exceedingly sensitive and completely anti-friction in character.

In Fig. 6 I show the present improvements adapted to the exact type of bearing shown in my former patent, this bearing being adaptable for carrying out the present invention by simply beveling the-adjacent rners of the annular parts t and u affixed t the hub. v

The object in :makin-g the flanges p q re movable from their sleeves is. notonly to render assembling of the parts ea-sy but also to render it ea'syto compensate for wear of the, parts that may. take place from use. Should the parts of the thrust bearingwear sufficiently to require adjustment, the flanges p gf may be removed andv their annular flanges `fu ground off sufficiently to bring these removable flanges closer to the opposite stationary flanges. It will be seen that these flanges v abut annular shoulders on the respective sleeves n and o, so that when they are` ground offl and replaced, these flanges will slide farther onto the sleeves and thus bring their friction faces closer to the adjacent race ring and thus compensate forjwearin parts of the thrust bearing. .It will be seen that theV annular flange 'u projects beyond-the beveled part of the ring, so that a considerable part of the flange fu may be ground off to take up wear, as stated, without affecting the bevel in the least.

It will be observed that the sleeve a is held removably in the hubby the bearing sleeve e and that thev inner sleeve a is clamped in place on the axle between a sleeve w and the sleeve d, said sleeve w being in turn `clamped in .place removably by means of the removable outer bearing sleeve d. It Will be observed that there is a clear-v ance y between sleeve o and the axle; the purpose of this is to insure the sleeve'o be` trued by the simple rotation of the hub, tlllligs f truing operation being brought about before the sleeves d and lw are clampedup tightlyv by the axle nut It will be understood that, this invention is equally applicable to a bearing in which the inner or shaft member rotates in a. stationary or box member and that in 'this case the annular clearance y will be arranged for between the outer sleeve u andthe stationary or box member.`

It will be understood, also, that instead of having. race rings hanging on the inner member of the axle, they may be supported upon the /outer member when said member is a stationary box instead of the rotary hub. It will be understood also that the details of the construction of my bearing mayfbe departed from Without departing from the spirit of my invention.
